Glossary: Missing a term for environment, site, ....

I am missing a term for the thing which holds all those nice python libraries.

How to call the container where pip/wheel ... installs the software into?

How to call the one thing which is allowed to provide a sitecustomize.py?

I asked on python-ideas an this project was mentioned. Maybe we can find
a matching term together.

Python-Ideas thread:

https://groups.google.com/d/msg/python-ideas/XNgEK4lbxt0/SDnuYHAXNQAJ

Up to now I found these terms:

• Project https://docs.djangoproject.com/en/1.8/ref/applications/#projects-and-applications
• Application https://caremad.io/2013/07/setup-vs-requirement/
• site https://docs.python.org/3/library/site.html
• complete python environment https://packaging.python.org/en/latest/requirements/

I don't care at all which term gets chosen. My intention is to find an agreement.

What do you think?

Start by reading the linked Python-Ideas thread and the referenced Django, packaging, and Python site documentation to compare the proposed terms. Done means reaching agreement on terminology and recording the chosen term in the project's glossary, but the issue does not identify a glossary file or a concrete wording change.
